After a lower intake gasket change I had misfire and general poor running conditions. After checking almost everything I finally could had a diagnostic tool available and the result is High Frequency on the CKP sensor (P0338).
I recon that I don't know where to start.
I know that one socket have been damaged while re-mounting the intake, could this be related to the CKP sensor?
What does mean high frequency on this sensor : faulty sensor or another trouble in the engine that is revealed by this CKP data?
Any help appreciated as I cannot use my truck for more than one month know( and spending many €uros around…)

Thanks for your informations, I'll probably change the sensor and see what's happening…another 100 bucks. For a while I had the engine that sometimes was staying stuck when I was cranking. I taught it was a faulty starter engine but in fact I guess this sensor is the true culprit.

Thanks for your help RaginInferno, I guess you should come here in France for vacation and have great time tuning my truck. We got nice beaches, good food and good party in summer lol.
Do you know where I can locate the crankshaft sensor on a 98 win W 4.3?

haha...last time I was there, I was in Deauville, Trouville and Saint-Gatien (Airport)... I speak a good bit of Cajun French so we could hang out!

...and yes, the Crankshaft sensor is on the bottom of the timing cover, passenger side.
